IK - I'm d4 - useless
Rocket enhancement - useless for everyone
10% more gold on purchase - useless
20% more productivity - I don't have companies - useless
50 gold from Monetary Market - I don't plan to buy that much - useless
Power Pack - I already own it, it would be useful if they didn't stack - useless

So only Blitzkrieg pack, 10% more rank, 10% more gold from achievements and division switch can be useful for me.

it is stacked. and non paying players can experience the packs. i expect they might do this a lot which means we can save some money in the long run. idea would however be to like the traveling tickets never spend any money to actually get a reward.

When a Division 4 player receives an Infantry Kit, the Experience Inhibitor Enhancement is disabled by default. This means that the Division 4 players will continue to gain Experience Points when fighting with weapons, even if they purchase the Infantry Kit.

Players in Divisions 1, 2 and 3 will have the Enhancement enabled as always.
